Question

我有两阵列和守则,以找到阵列:

$obs_ws = array("you", "your", "may", "me", "my", "etc");
$all_ws = array("LOVE", "World", "Your", "my", "etc", "CoDe");

$final_ws = array_diff($all_ws, $obs_ws);

产出阵列之上:

$final_ws = array("LOVE", "World", "Your", "CoDe");

但我希望:

$final_ws = array("LOVE", "World", "CoDe");

注 “Your”没有删除,这可能是由于“Y”在第二阵列中的上限。我也想排除“Your”一词,因此,在PHP中,对array_diff的任何不敏感版本。

我尝试了<array_udiff,但我并没有确切了解如何在我的问题中使用这一方法。

Answer 1

Try to adopt strcasecmp , as third paraile to 职能:



<?php
$obs_ws = array("you", "your", "may", "me", "my", "etc");
$all_ws = array("LOVE", "World", "Your", "my", "etc", "CoDe");

$final_ws = array_udiff($all_ws, $obs_ws,  strcasecmp );

print_r($final_ws);


产出:

Array
(
    [0] => LOVE
    [1] => World
    [5] => CoDe
)

Answer 2

你们已经走上正轨。这是我的建议:

function array_casecmp($arr1,$arr2){
    return array_udiff($arr1,$arr2, strcasecmp );
}


$obs_ws = array("you", "your", "may", "me", "my", "etc");
$all_ws = array("LOVE", "World", "Your", "my", "etc", "CoDe");
var_dump( array_casecmp($all_ws,$obs_ws) );
